摘　　要：[目的]分析比较常见夹竹桃科植物叶片颜色及类胡萝卜素含量。[方法]以3种常见夹竹桃科植物叶片无性繁殖材料为研究对象,使用丙酮、酒精混合液萃取后,用分光光度计测定待测材料的胡萝卜素、叶黄素和总类胡萝卜素的含量。[结果]3种常见夹竹桃科植物叶片颜色不同,胡萝卜素、叶黄素和总类胡萝卜素的含量有所差异,含量趋势均为鸡蛋花>夹竹桃>黄婵。[结论]3种夹竹桃科常见植物的叶片颜色与叶片内类胡萝卜素的含量有关,含量越高,植物叶片颜色越深,植株生长的也越高。[Objective] The leaf color and carotenoids content of 3 common apocynaceae plants were comparative analyzed.[Methods] The asexual reproduction materials of 3 common apocynaceae plant leaves were to be the research object,after extraction process used the mixture of acetone and alcohol,the content of carotene,lutein and carotenoid in test material were measured by spectrophotometer.[Results] The Leaf colour of 3 common apocynaceae were different,and the content of carotene,lutein and carotenoid were distinct between 3 plants,and the content reduce trend were Plumeria rubra′ L.cv.Acutifolia′,Nerium indicum Mill,Allemanda cathartica L..[Conclusion] The leaf color of 3 common apocynaceae were related to the carotenoid content in leaves,the higher of carotenoid content,the darker of the plant leaves color,and the plant growing taller also.
